Alphard 2003 Comfort/Sport switch

[Mario-R]

Hi guys. 
Being new owner of Alphard 3.0 -G series hoping that you can help me with better understanding of Comfort/Sport switch. I’ve also seen electrical box (?) on the top of the struts. Just wondering how this is operated. I cannot see any air lines so doesn’t look like pneumatic suspension to me. It’s more like electrical dampening thing (?)  Can someone can explain that to me and other members how this is working, what components are involved etc and if it’s reliable or not, what to expect in the future from this system? Appreciate for any help

I can only see difference when driving at higher speeds and when I switched from comfort to sport car automatically stopped floating like a boat. Nice feature, hope it’s reliable but should be as it’s Toyota
